摘　　要：在研究永磁超环面电机结构与驱动机理的基础上,分析计算了该电机的电感,并建立了该电机的数学模型。基于无位置传感器控制的优点,设计了基于模型参考自适应(MRAS)的永磁超环面电机无位置传感器控制系统,并进行了该控制系统的仿真。仿真结果表明,基于MRAS的永磁超环面电机转速估计误差较小,模型参考自适应控制系统能实现对行星架转子角速度的高精度辨识,该控制系统控制效果良好。Based on the analysis of the structure and driving mechanism of the permanent magnet toroidal motor, the inductance of the motor was analyzed and calculated, the mathematical model was established. Based on the advantages of position sensorless control,the position sensorless control model based on model reference adaptive system( MRAS) applied for permanent magnet toroidal motor was designed, the simulation of control system was established. The simulation results show that the motor speed and the position angular of the planet carrier rotor error based on MRAS are small, the control system based on MRAS can estimate the planet carrier rotor angular speed accurately, and the control method is effective.
